A collection of electrical schematics, mechanical drawings, and other drawings for Block II AGC models 2003100 and 2003200 and their associated DSKY models. This imagery comes from 8.5"×11" photocopies of what were originally much larger drawings in some cases.  The photocopies were then stored in a binder for 50 years before finally being digitized.  The quality has therefore been compromised not only by the size reduction of the originals, but also by the long storage time.  In...

Apollo Guidance Computer software, not used for any flown mission, though theoretically targeted for the Lunar Module.  As of February 2017, it is the oldest-known still-surviving AGC code.  At the time it was written in 1965, its purpose was to port AGC code written for the Command Module's early "Block I" AGC to the later-model "Block II" AGC used for the flown Lunar Module missions.

"FCC" stands for Flight Control Computer, from the Instrumentation Unit of Saturn V and Saturn IB rockets used in the Apollo missions of the late 1960's and early 1970's.  In modern terms, the word "computer" is a misnomer: The FCC was not a digital computer, nor does it run software.  You can think of it as an analog computer whose primary function was to reduce attitude errors in the rocket: i.e., to help prevent it from flopping over in flight. Here's a rough index to...
